SoA-only Wizard Slayers can only use Restoration scrolls, Resurrection rods (I think), and green (cleric) protection scrolls. Wizard Slayers with ToB installed can use those items, plus healing potions, antidoes, and one other potion (can't remember what it is ATM), and can use them in both SoA and ToB areas.
I wouldn't know. My Wizard Slayers think potions are for sissies.
